Abstract (en)
A dry disconnect coupling (10) for connecting one fluid conduit to another fluid conduit to form a continuous flow path, said coupling comprising a receptacle (20) and a coupler (30), each being secured to a respective conduit or container, with means for securing and locking the receptacle and the coupler together to provide a connection for transfer of fluids, a poppet valve (212) seated in each of the receptacle and the coupler for sealing a respective flow passageway therein when the coupling is uncoupled, and which valves can be unseated to permit flow of fluid through the coupling when the coupling is coupled and locked; the poppet valve of the receptacle having resilient annular sealing means (220) in its poppet sealing surface; the coupler body and poppet and the receptacle body and poppet being provided with resilient annular sealing means at their interfaces, the coupler poppet being self-aligning, the arrangement of the sealing means and the geometry of the coupler body and poppet and the receptacle body and poppet being such that a small interface between the two poppets is provided whereby only a minimal volume of fluid remains in the coupling after uncoupling. <IMAGE>
